## Verdict

Filen is the open-source alternative to Tresorit. Same end-to-end encryption story; younger operator. Useful when open-source clients are a requirement.

## Strengths

- Open-source clients (desktop, mobile, sync).
- End-to-end encryption at rest with client-held keys.
- Crypto payment accepted on paid plans.

## Caveats

- Email at signup.
- Germany jurisdiction.
- Smaller operator; mature compared to peers but younger than Tresorit.
- Facts need re-verification by operator (last seeded 2026-01).
